"Scarlett" is a hand crafted top hat made out of foam with the appearance of aged wrought iron that has been tinted red. Even from just a few inches away it looks like actual sheets of metal were riveted together to form the hat.
The "Scarlett" narrows in the middle giving it a "Mad Hatter" appearance and it has a gold keyhole and key with a smoke stack coming out of the top.
The hat shown is an example of this design. All hats are individually hand made and while largely similar in appearance some minor variations should be expected.
